NASA is seeking Heliophysics research proposals focused on low-cost access to space through its ROSES-2025 program.
- **Buyer:** NASA Headquarters, NASA Science Mission Directorate (SMD), through the Research Opportunities in Space and Earth Sciences (ROSES-2025) announcement.
- **Opportunity:** Heliophysics Low-Cost Access to Space, program element B.7.
- **Requested work:** Research and technology proposals involving low-cost access to space; no specific products, services, quantities, or part numbers are identified.
- **Proposal requirements:** The solicitation uses a binding two-step submission process. The anonymized central Science-Technical-Management section is limited to 20 pages. Proposals must include a separate Payload Reference Document and a Rideshare Opportunity section; science-enabling-only proposals must also include an Application of Traceability Matrix.
- **Evaluation and data management:** NASA uses dual anonymous peer review, so the technical proposal must be anonymized. An Open Science Data Management Plan using the standard SMD template is encouraged.
- **Potential awards and performance:** Awards may be grants or cooperative agreements. A typical period of performance is three years, with some programs allowing up to five years or specifying a shorter period.
- **OEMs and vendors:** None are named.

### Description

This NASA ROSES-2025 program element solicits proposals for Heliophysics Low-Cost Access to Space.
